Outline of Final Research Achievements

The following research was conducted with the aim of inducing oxygen vacancy and electron introduction when reducing and firing a solid solution of Mg-Al oxide to induce conductivity to Mg-Al oxide, which is originally an insulator.
1. The structure of the Mg-Al LDH fired body was analyzed and the oxide ion conductivity of the Mg-Al LDH fired solid solution was investigated. A reduction in the bandgap was observed in the LDH calcined product compared to MgO. In addition, ionic conductivity was observed in a slightly high temperature region.
2. Calculation of the electronic state of the LDH fired body: The electronic state of the Mg-Al LDH fired body was calculated using the SPR-KKR method, which can accurately calculate the solid solution. As a result, the reduction of the bandgap due to the addition of Al was reproduced in the calculation.

Academic Significance and Societal Importance of the Research Achievements

欠陥導入と電子注入による、本来絶縁体である金属酸化物のバンドギャップ低下、導電性付与法の開発を行った。本研究が完成すれば、安価な半導体材料等の新材料開発が期待できる。
